Abstract
Titanium wear is a growing area of interest within dental implantology. This study aimed to investigate titanium and zirconium wear from dental implants at the time of insertion using X-ray-fluorescence spectrometry (XRF) and an in vitro protocol utilizing artificial bovine bone plates. Five groups were analyzed using XRF-spectrometry: groups 1–4 (titanium implants) and group 5 (zirconia implants). The implants were inserted into two bone blocks held together by a vice. The blocks were separated, and the insertion sites were analyzed for titanium (Ti) and zirconium (Zr). Statistical descriptive analyses of Ti and Zr concentrations in the coronal, middle and apical bone interface were performed. A comparative analysis confirmed differences between the implant’s surface stability and Ti accumulation within the insertion sites of the bone block. There was a direct relationship between implant length and the quantity of titanium found on the bone block. The data generally indicates greater quantities of titanium in the coronal thirds of the implants, and less in the apical thirds. The titanium and zirconium found in the bone samples where the group 5 implants were inserted was not of statistical significance when compared to control osteotomies. The results of this study confirm wear from metallic, but not ceramic, dental implants at the time of insertion.
Highlights
Dental implants have become a popular option for the replacement of one or more missing teeth due to their versatility, survivability, biocompatibility, and predictable results [1]
The aim of this study was to investigate the process of wear from metallic and ceramic implants at the time of implant insertion using X-ray-fluorescence spectrometry (XRF) spectrometry and an in vitro protocol, according to which the implants were inserted into artificial bone plates
The spectrometric analysis detected the presence of Ti on the bovine bone blocks following titanium implant insertion in dense bone
Summary
Dental implants have become a popular option for the replacement of one or more missing teeth due to their versatility, survivability, biocompatibility, and predictable results [1]. Implants may be used for both single- and multiple-unit removable or fixed prosthetic dental restorations. This is an area of critical importance in dentistry due to the prevalence of edentulism in the population [2,3]. The surgical process of implant insertion into bone is complex. Bone density is modified by the surgical insertion of a dental implant as there is a dynamic balance between bone removal and condensation [6]. This balance exerts an important influence on the morphological features of the biomaterials used in implant therapy. Biomaterial research has become an area of great interest in implant dentistry
